Abstract:
High-capacity, underground high-temperature superconductor (HTS) cable capable of
accommodating large power requirements is one of the new, low-profile technologies to
solve grid reliability problems with great promise. The current lead is one of the
significant components in a superconducting transmission system. In order to reduce heat
conduction from the current lead into cryosta... read morets and maintaining the cryogenic stability
of the system and its cost effectiveness, using thermoelectric materials for Peltier
cooling effect is a promising strategy. This thesis focuses on computing the temperature
profile of such Peltier-cooled current leads. COMSOL Multiphysics has been used for the
one-dimensional model building in this thesis, and a positive result, i.e., that Peltier
cooling would reduce the heat conduction by 10% for typical conditions has been
obtained.
